Figs.v 13 and 14 show a vmodification of the valve device according toFig. 11.

The outfit (Fig. 1) comprises a toothbrush 1 provided with a shank 2whose ta-v pered en'd fits exactly `in to a corresponding aperture 3formed the hollow handle 4. By this arrangement the-"brnsh is Awell se:cured to its handle and at' lthe same time the aperture 3 is closed, sothat'the chamber in the interior of the handle 4"will serve to contain adentifrice inthe ,form of a liquidV or a paste, or even a' owder.

To enable Jhe use o a liquid dentifrice in the Qhamber 5, vI Provide at'the end'of- Said the accessories' s uch as dental chamber a clesnmissen o .f air and 11) e Serevthaeaded rv. 6 whlch is provided with econtrolling handle 8 and whose Peinted end '8 serves to .los thetransverse chan` des@ sawing :he f1-: .com rising (Flgf 2 and' position;as Shown in Fig- 5.,'a1id the handle isoperated vin order to rotate thevalve rod 5 so that .the denti-ffice contained .in Said chambermay bedischarged in the form of liroys whlch .can be Spread 1190.11 the brushthe position represented in Fig. 9, an is then ,ready for use The handle4 carries an internal screw 'thread in @the rear ,of the wall 10, whichis adapted for the insertion .of a plug 12 in which is formed a suitablerecess, for instance of cylmdric'al shape, adapted to contain -a spoolV13 of dental silk thread. In the ,end of the plug l2 is formed anaperture 14 for the egress .of the silkthread 15, and

The chamber 5 may contain, insteadof a liquid dentifrice, afdentifrice 1n the form of a paste, or even apowder, which may be introduced in any suitable manner, for instance bydividing the said chamber l into sections which allow the introductionof a paste or a powder in bulk, or of intermediate recipients containingsuch (paste or powder, which may be com resse 1n an adequate manner forthe disc arge of their contents.

The valve device 6 8 shown in Fig. 11 and controlling the inlet of airinto the chamber 5 could be replaced. by a valve or plug 24 such asshown in Figs. 1 4 and 15, provided with an operating projection 25 andkept in closing posit-lon by means of an elastic ring 26.
